If any damage is detected, please report immediately, and notify the shipping company thereof. After unpacking, any remnants of wrapping materials should be cleaned off the units and accessories. Until their installation, these should be protected from damage, humidity, and soiling. For handling, the switches should be taken up by their frame only, and under no circumstances by their vacuum poles. Operating conditions Installation can be carried out at heights of up to According to this the following limiting values applies: 000 m above sea level. At heights above 000 m Ambient temperature: the rated insulating level of the switchgear must be Peak value of the ambient temperature +0 C corrected accordingly. Average value over hours + C The switches are designed for normal operating Min. value of the ambient temperature - 0 C condtions according to EN 67-. (class minus 0 Outdoor ) Commissioning Before mounting on the concrete column the stopper screws on the case of the switching chamber should be removed, the oil level must be checked (0, Liter Shell Diala D oil, see maintenance instructions) and the provided ventilating plug must be screwed in. Connecting of switches Conductor bars, or cable sealing ends Please make sure that switch terminals are not twisted. Neither transverse nor tensile nor torsional force should be applied to the switch terminals. The M terminal screws should be tightened using a torque of 70 Nm (with a second spanner used for countering). Particular attention should be paid to the requirement that electrical clearances should not be less than those specified, and that the mobility of the rotary post insulator should not be impaired. Preparation of earth connections The frame contains the appropriate boreholes for holding the M earth-connection screw. The minimum cross section of the earth-connection terminal leads should be 0 mm. If assembly is carried out on an earthed supporting structure, the necessary earth connection may already be provided with the mounting of the unit if the appropriate contact washers are used. Assembly instructions for FLa /600 / 60 mounted to a concrete column A With single box-type actuator or L-actuator. On its conduit section, the L-actuator has a threaded coupling for connecting the lower linkage rod. For the box-type actuator 7, mounting is carried out through the bushing contained in the actuator tube.. As a rule, actuators are arranged at 90 laterally to the switch (the crank of the actuator shaft is fastened outside the centre of the switch).. In this arrangement, a reversible bearing, type 7, serves as the up-permost guide and, simultaneously, for reversing the direction of thrust. Fastening to the column is carried out using two M 6 x 00 screws.

3 Assembly instructions for FLa /600 / 60 / SA mounted to a concrete column B76. Depending on the length of the column, the linkage rod is guided using or intermediate bearings. The intermediate bearing preceding the reversible bearing is provided with a link bushing which enables the linkage rod to deflect sideways. This intermediate bearing is marked with a red label. Fastening to the column is carried out in the same way as for the reversible bearing.. The distance between the bottom and the centre of the actuator box, or mechanism assembly, should be 0 mm if possible. 6. It is to be recommended that actuators should be mounted with the column in horizontal position. 7. Setting of the operating mechanism must be carried out with the switch in closed position. 8. Any tensions within the linkage are to be compensated for by loosening the clamps on the stub heads. 9. The boreholes in the clamp-on 6 crank provide a possibility of setting the operating path (cf. illustration, crank position). 0.When fixing switches in place please make sure that frames are not distorted by uneven surfaces. If appropriate, use a backing to compensate for unevenness..the switches have been designed so as to ensure that there is no need for linkage crimping. The switch has been set correctly if it reaches the ON and OFF positions even when the actuator is being operated slowly in both directions..after several trial switching operations, all terminal and fixing screws, in-cluding those for clamping stub heads and clamp-on cranks, must be re-tightened. B Concrete column with dual box-type actuator. For operating these switches with attached earthing switch, a dual box-type actuator is used 7. The operating levers are mechanically interlocked with each other within the box. Any inadvertent wrong operation is thereby ruled out.. The dual intermediate bearing provided 8 with a link bushing (marked with a red label) guides the linkage mechanism. 6 Crank position Insertion and replacement of h.v.h.b.c. fuse links Type /60 SA (see cover picture): Switch off the switch-disconnector positioned above the fuse links. Take up the h.v.h.b.c. fuse links with handling tongs (Order no. 7700, List 77) and insert in the fuse mounting contacts in such a way that the striker pin can operate the tripping mechanism. (Observe marking on h.v.h.b.c. fuse link) When a h.v.h.b.c. fuse blows we recommend also replacing the two other fuses due to possible ageing caused by overcurrent. 8 7 L-actuator dual box-type actuator

4 B76 Assembly instructions for single-pole FLa /60 mounted to a concrete column A Breaker poles (for wide-spanned systems) The breaker poles are each marked with a date and a number. Please make sure that in each case only poles marked with the same date and the same number are assembled. The single poles are preassembled, i.e., mounted to the cross arm of the column using M 6 x hexagonal screws each, and connected to the coupling shafts. Settings for kv and 6 kv load-break switches In order to prevent the coupling shafts from falling out of the coupling sleeves, the securing clips included in the scope of delivery must be attached. Any unevenness in the cross arms of the columns should by all means be compensated for by using washers. Prior to setting the operating mechanism, the single poles shall be attached finally, in true alignment, to the cross arms of the column. B Box-type actuators (travel, 0 mm). The FLa /60 outdoor load-break switch without earthing switch is operated using a single box-type actuator. The actuator tube used for this purpose contains a bushing for fastening in the actuator box.. Actuator box and linkage mechanism should always be arranged at 90 to the cable run.. The actuator box is attached to the concrete column using M 6 x 00 hexagonal screws. The boreho les used for fastening will be accessible after the lid has been opened.. For guiding the linkage,, 6, or more inter mediate bearings, should be placed, depending on the length of the column. For fastening the intermediate bearings, M 6 x 00 hexagonal screws are required.. In the single stub head of the upper intermediate bearing, there is a link bushing which enables the linkage rod to deflect sideways. That intermediate bearing is marked with a red label. 6. The clamp-on crank 8 is mounted to the shaft of the switch between the pole frame and the support bearing 9. If no support bearing is used, the clamp-on crank should be mounted as closely as possible to the centre of the pole frame. 7. For hinging the linkages, illustrations a, b, c, as well as positions 7, 8 should be observed. 8. Setting the actuator may be carried out with the switch in ON position only. If the operating mechanism is set prior to guying the overhead conductors, re-adjustment of the operating mechanism after guying will be absolutely necessary. 9. The upper linkage rod 6 with the clamping stub head 7 is to be connected with the clamp-on crank 8. 0.The switch will be adjusted correctly if it reaches the ON and OFF positions even if the actuator is being operated slowly in both directions. The end stops for the ON and OFF positions have been marked in a clearly visible manner on each switch..any tension in the linkage should be compensated for by loosening the clamping stub heads of the intermediate bearings, with nuts to be retightened the reafter..after several trial switching operations, all terminal and fixing screws, including those for clamping stub heads and clamp-on cranks, must be retightened. For operating outdoor load-break switches, dual and triple-box actuators are used with one or two earthing switches attached (cf. illustrations b and c )..The clamp-on cranks 8 are also to be fastened to the earthing-switch shafts, as closely as possible to the centre of the pole frame. For central switch poles mounted to sub-frames, earthing-switch shafts are on the fixed-mounted post-insulator side connected mechanically to an intermediate shaft positioned in the subframe. The clamp-on crank 8 is attached to that intermediate shaft..for hinging the linkages, illustrations a, b, c as well as 7, 8 positions should be observed.

Switch connection is carried out using the flexible copper strips,.. The fork-type lugs are intended for fastening the copper strip. Assembly of operating mechanism. For operating the outdoor load-break switch, L - actuators or box-type actuators are available 9.. The operating mechanism and the intermediate bearings, should be mounted at to the cable run.. The operating mechanism should be fastened at a height of approx. 0 mm above ground, and mounted to the column using drawstrings or M 6 screws.. For columns of an unsupported length of up to 0 m, the linkage will be guided by single intermediate bearings, 6. Fastening of the bearings is also carried out using drawstrings or M 6 screws. The upper intermediate bearing is provided with a link bushing which enables the linkage tube to deflect sideways. That bearing is marked with a red label. 6. The load-break switches have been designed so as to ensure that there is no need for linkage crimping. Please avoid crimping! 6. It is recommendable to mount the switch with the column in horizontal position. The linkage, however, may be tightened only with the column in vertical position. If the operating mechanism is mounted with the column standing upright, and set prior to the guying of the overhead conductors, readjustment of the operating mechanism after guying will be absolutely necessary. 7. The clamp-on crank 8 with clamping stub head 7 is to be mounted as closely as possible toward the central switch pole (for crank position, see illustration A). 8. The switch has been set correctly if it reaches the ON and OFF positions even when the actuator is being operated slowly in both directions. The end stops for the ON and OFF positions have been marked in a clearly visible manner on each switch. 9. Any tension in the linkage should be compensated for by loosening the clamping stub heads 7 of the intermediate bearings, with nuts to be retightened there after. 0.After several trial switching operations, all terminal and fixing screws, including those for clamping stub heads and clamp-on cranks, must be re-tightened. Note: For the FLa /60 W type (horizontal), please make sure that the actuating crank for the post insulators is brought into dead-centre position to avoid any inadvertent closing of the switch in case there is a defect in the operating mechanism. For this reason, the actuating angle is 0. (The function of a dead-centre circuit.) Secondary connections (optional) Provide the auxiliary switch connections as shown in the enclosed wiring diagram. Secondary wires are to be shielded against the high voltage area. Testing the auxiliary switch: (optional) The auxiliary switches are factory set and tested on all functions. A function check is to be done after the assembly works. Supposed that an auxiliary switch is mistakenly adjusted during transport or assembly works, it is to be checked and if necessary readjusted.

8 B76 Inspection Maintenance Repair General Our products have been on the market for many years, and thousands of them are in operation. This is why we can claim that the quality of our products offers a high degree of robustness and operational dependability. In order to be able to guarantee that the requirements made on the units are met, and in order to avoid any power failures, we would like to state that for the purpose of a reliable energy supply, it will be necessary to subject the units to maintenance, inspection and, if appropriate, repair, depending on the operating time and operating frequency of the switchgear as well as on the amount of the nominal current switched Inspection For load-break switches, inspection should, in addition to regular visual control, be carried out after approximately 0 years or 000 operations even if the operating frequency of the switchgear is low, and only minor loads are applied. Shorter intervals of inspection may apply in the event of: aggressive environmental impact; special cases of application; high operating frequency. Maintenance Prior to commencing work, the working area must be isolated and safeguarded observing the safety regulations in compliance with DGUV V (regulations of the statutory insurance institute of the industry). Always observe the local safety regulations. Maintenance will essentially be limited to lubricating main contacts and bearings, as well as to the control and cleaning of insulating parts. It is necessary to check the oil level in the switching chamber after approximately 00 switching operations. The oil must be changed after 0 years of use. In the event of fault, the complete chamber should be sent to the factory for overhaul work. After loosening the two fastening screws, it will be possible to remove the complete chamber. a) Clean the contacts using petroleum ether or special purifier, depending on the degree of soiling, and use a lubricant of low viscosity (recommended product: BARRIERTA L / made by the company Klüber). b) Check all bearings and links for ease of movement, and lubricate using Rivolta S.K.D. 6 N spray made by Bremer & Leguil. c) Clean the insulators if dirty. d) Check the unit for proper switching function by carrying out a few trial switching operations. e) Check all bolted connections, in particular the clamping screws on the actuator crank. Repair Please install and remove switchgear parts and accessories only after the switch has been set to OFF position, and the work area has been enabled and secured in accordance with regulations under DGUV V. It is particularly because of the requirement of correct adjustment that disassembly as well as the installation or removal of switchgear (parts) should only be carried out by our DRIESCHER staff or professional personnel having received proper instructions. Switching chamber- sectional view Oil filling equipment with measuring rod and ventilation. For checking the oil level after approx. 00 switching operations, the ventilating equipment with measuring rod should be placed without screwing. The oil must be changed once in 0 years. Approximately 0, liter Shell Diala D oil is required per switching chamber.
